Kei

ケイ

A young woman Kaneda encounters while searching for Tetsuo. She belongs to an anti-government organization that also includes Ryu and Nezu.
She appears somewhat older than Shotaro Kaneda in the manga, just as he looks younger, and seems more attractive there as well.
Kei's role in the Resistance is significant due to her complete loyalty to its cause and to Ryu. Her character is much more developed in the manga, where she serves as more than just a "hard-to-get" love interest for Shotaro Kaneda. She is strong-willed and is the one who discovers that Lady Miyako is also an Esper. Miyako helps Kei channel her thoughts, revealing that she is a conduit for the Espers' telepathy. In the movie, Kiyoko performs this function, and Kei communicates with Kaneda and Tetsuo. She works closely with Chiyoko, a physically strong and resilient resistance fighter, and they look out for each other.
